I think there's definitely an opportunity to do so. Whether it should be mandated, I think, would not be something for QUEST to answer. I do think if we look to the U.K., for instance—and this is perhaps more on the retrofit side than on the new-build side—we see they have a requirement whereby they actually have to document what the efficiency of that building is before it is sold. It actually incents this position when new homeowners actually know the status of that building. It also helps to encourage the retrofit economy to take place.
There are lots of great examples outside of Canada that we could draw on.
